| 摘要 | A development device includes a developer carrier configured to supply developer on a latent image formed on a latent image carrier to visualize the latent image. Wherein the developer carrier includes: an elastic layer formed on an outer circumferential surface of a conductive support body, the elastic layer including urethane rubber; and a top layer formed by treating a surface of the elastic layer with treatment solution that includes urethane polymer, silicone-based additive and conductive agent. The top layer includes convex parts that include the urethane rubber and concave parts in which the silicone-based additive and the conductive agent are laminated. | ||
